U60 runs debian/etch, nfs-kernel-server, and client I use for tests is
a i386 (K6-3/400) that runs debian/etch too. I have tested different
memory configuration and the oops always occurs at the same instruction.
Any idea ?
Any chance you can test a gcc-4.0.x compiled kernel?
This might be a miscompile.
Some news... I have rebuilt a 2.6.19.1 kernel with gcc-3.4 (version gcc
3.4.6 (Debian 3.4.6-4)). I obtain a similar Oops :
